Functions ¶

func ConvertPort ¶ added in v0.2.0

func ConvertPort(namespace, name string, port *corev1.ServicePort) corev1.ServicePort

func Execute ¶

func Execute()

Execute adds all child commands to the root command and sets flags appropriately. This is called by main.main(). It only needs to happen once to the rootCmd.

func GetClassName ¶ added in v0.2.0

func GetClassName(ing *netv1.Ingress) (string, bool)

func PortName ¶ added in v0.2.0

func PortName(namespace, name string, port *corev1.ServicePort) string

PortName produces a predictable port name from a guest service. This is done in a way that can be matched in the helm chart, allowing us to create static ingresses for guest NodePort services without knowing their assigned nodeports ahead of time, and without imposing further name length restrictions. This works by taking a 32-bit checksum of the "namespace/name/portname" of the port, then formatting as hex, padding to a max of 8 characters with a prefix
